INKING DEVICE FOR ADERESSING LVEACHINES.

Application filed. ctoher 18, 1920.

To @ZZ fio/wm it may concern:

Be it known that l, Cmrroii Giusi-rotar, a citizen of the United States,residing at Cleveland, in the county Cuyahoga and State of Ohio, haveinvented a certain newv and useful Improvement in nking Devices forAddressing Machines` ott which the following is a full, clear,and-'exact'description, reference beingk had to the accompanyingdrawings. v,

rEhis invention relates to a mechanism for inking address plates inan'addressing machine as they are passing from the supply to addressplate, or its holder, were inked. At. the same time, this mechanismprotects the transfer roller from being injured by undesirable contactwith the plate holder.

Other features of the invention relate to carrying a proper supply ofink in an absorbent roller, and the ready loading ef such roller, and tomaintaining proper adjustment between the supply4 roll and the transei."roll,

and between the transfer roll and the plate.

rllhe invention is hereinafter more fully..

ezqilained in connectionr with the drawings illustrating an approvedembodi in enttliiereof.

In the drawingsy Fig. 1 is sectional elevation of `my ink mechanism;Fig. 2 is an end view thereof; Figs. 3, 4 and 5 are vertical sections onthe 4correspondingly numbered lines of Fig. 1

The frame of the machine shown kcomk position roller 30 mounted on theVshaft 31,

whichhas bearing blocks 32 housed in open-r ings l33 inthe standards. Asshown in Fig. 3, the blocks rare guided onV their vertical sides, Whilemovement is allowed in avertical direction, The blocks are presseddownwardly by compressionsprings 35k mounted.l

Serial NO. 417,579.

in facing cavities respectively in the upper part of the block and theunder part of a cap plate 1'5 extending across and forming the top `ofthe standard 11.y rfrlignment of the bearings with the shaft Xis isrmainf tained by vertical pins 37 carried by the blocks and extendinginto vertical Aopenings 18 in the standards.y y

Above the composition roller is a felt supply roll 40. This roll iscomposed of a large number of annular pieces of felt mounted on aperforated tube 41. At each end anged bushings 42 and 43 screw into theAtube 41 and serve to compress the felt rings, suitable washers 44 beingplaced between the flanges ot the bushings and the felt. At one ,end thebushing 42 has rigidlysecured `toit, ak stud 45, which forms a gudgeonfor carrying the roller.` At the other enda gudgeon 46 is provided, butthis" gudgeon has a vscrew threaded engagementwith the bushing 43, sothat-it may` be readily removed for loading the/roller.` Each gudgeonhas its shankoccnpying a vertical slot 19 rinthe cap member Suitablecollar portions 47 on the gudgeons serve to center the roller. frittheir outer ends the gudgeons have knurled knobs to enable convenienthandling.

rllhe sectional construction of ther felt roller described enables it tobe cheaply made,v and, repairedfrom time totiineby the substitution ofnew -felt rings, andenablesalso its convenient loadingwhenever desired,-the roller being simply removed and held vertical, ythe gudgeon 46screwed out. the ink supplied and the vgudgeon returned lto position. yTo maintain aproper the yfelt roller and the `composition rtransferroller, I provide a kpair of hooks 50 pivotally secured at 51 to theblocks 32, and

k feet this, I providebearingl rollers-.610 on 'the pressure betweenkshaft 31, arid I form depressions a in the hollow ribs forming the endportions of the plate opposite the region of the printing characters.When the ,plate is passing thru the machine, the portion thereof inadvance of the depression a engaging the bearing rollers 60 raises thecomposition roller so that it cannot contact with the plate holder,thus, it is neither injured itself, nor does it smudge the holder. Justbefore the type portion of the plate reaches the composition roller thedepressions a in the plate holder are presented to the bearing rollers60. Then the composition roller under the action of the springs 35 movesdownwardly and contacts with the type characters. As soon as thesecharacters have been inked the portion of the plate holder beyond thedepressions a again raises the composition roller to inactive position.

It should be noted that the plate holder having the edge ribs with topdepressions illustrated herein forms the subject matter of myapplication No. 410,710, filed September 16, 1920.

Having thus described my invention, I

` claim 1. The combination, with an inking roller, of bearing rollerscoaxial therewith, and an address plate having raised and depressedportions adapted to coact with the bearing rollers.

2. The combination, with an inking roller, of bearing rollers coaxialtherewith, and an address plate having hollow ribs with raised anddepressed portions adapted to coact with the bearing rollers. j

3. The combination, with an inking roller, of bearing rollers coaxialtherewith, an address plate having ribs with depressed portions oppositethe region of the printing characters. and means for supporting theaddress plate, and for feeding it with the depression tangential to thebearing rollers.

4:. The combination, with an inking roller, of bearing rollers coaxialtherewith, an address plate having raised and depressed portions adaptedto coact with the bearing rollers and' rotary supporting rollers on theunder side of the plate opposite the ink roller. f

5. The combination, with an inking roller, of bearing rollers coaxialtherewith, an address plate having raised and depressed portions adaptedto coact with the bearing rollers, chains for advancing the plate, andmeans for supporting the chains below the hearing rollers.
